CPIC error when calling a external c program

[Former Member]

Hi All,

i Have a scenario where we call a C-Program(RFC api) to connect to and external system thru tcp/ip.

The issue here is when we call the c program from ABAP we get the below error in files

Dear Rajesh,

This depends on what your program does. Based on the error message, it looks like the program ends abnormally, as the gateway writes an error while attempting to read/write data from the connection to the program. With what you have given, the error does not seem to lie with the SAP side. You will have to check your program, e.g. using a debugger.

Best Regards,

Tim
